Product Description
U140E U140F U151E U151F U240E U241E U250E Lockup Control Plunger Valve Kit
Sonnax Part Number: 57917E-03K
NO TOOLING REQUIRED
Toyota/Lexus U140E, U140F, U151E, U151F, U240E, U241E and U250E transmissions use a lockup control plunger valve to appropriately position the lockup control valve for converter apply and release. Wear of this plunger sleeve can result in converter apply pressure exhausting, resulting in TCC apply & release concerns, TCC codes, and a burnt converter. Replacing the worn sleeve and plunger with Sonnax lockup control plunger valve kit 57917E-03K restores proper control at this location.
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves have been added to the valve to prevent sideloading-related wear
- Drop-in Zip Valve™ parts install quickly and easily
PACKAGE CONTAINS

SYMPTOMS

CAUSE
Continuous oscillation of the steel lockup control plunger valve wears the inside of the aluminum sleeve bore, allowing converter apply pressure to exhaust and preventing proper control of the lockup control valve.
CORRECTION
The tightly toleranced, drop-in replacement Sonnax lockup control plunger valve kit restores proper hydraulic clearances and uses upgraded materials to prevent wear.
